Glossary of Terms
Organophosphate (OP) insecticides: They act by inhibiting the enzyme acetylcholinesterase. Most are not persistent and do not bioaccumulate
in animals or have signifcant long-term environmental impacts.
OPs have a wide range of toxicities; some are neurotoxic.
Particulate matter: Fine liquid or solid particles, such as dust, smoke, mist,
fumes, or smog, found in air or emissions. Suspended particulate matter is fnely divided solids or liquids that may be dispersed through
the air from combustion processes, industrial activities, or natural
sources. (https://unstats.un.org/unsd/environmentgl/default.asp)
Pheromones: A pheromone is a secreted or excreted chemical factor that triggers a social response in members of the same species. (Wikipedia)
Semiochemicals: Chemicals involved in the biological communications
between individual organisms. Includes allelochemicals (chemicals
produced by a living organism exerting a detrimental physiological
effect on the individuals of another species when released into the
environment) and pheromones. (Wikipedia)
Semi-volatile organic compounds (SVOCs): A subgroup of volatile organic
compounds (VOCs) that tend to have a higher molecular weight and
higher boiling point temperature than other VOCs. SVOCs include
pesticides (DDT, chlordane, plasticizers (phthalates), and fre retardants (PCBs, PBB)). SVOCs have vapor pressures between 10 −5 and
0.1 Pa.
Stratosphere: The upper layer of the atmosphere (above the troposphere),
between approximately 10 and 50 km above the earth’s surface.

Toxic air contaminant (TAC): An air pollutant which may cause or contribute to an increase in mortality or an increase in serious illness,
or which may pose a present or potential hazard to human health.
(CARB: California Air Resources Board)
Troposphere: The layer of the atmosphere extending about 10 km above
the earth’s surface. (https://unstats.un.org/unsd/environmentgl/
default.asp)
Vapor: The gas phase of a substance at a temperature where the same substance can also exist in the liquid or solid state, below the critical
temperature of the substance. (Wikipedia)
Volatile organic compounds (VOCs): Organic compounds that evaporate
readily and contribute to air pollution mainly through the production of photochemical oxidants. Some VOCs are formaldehyde, toluene, acetone, ethanol, isopropyl alcohol, and hexane. (https://unstats.
